Cr12MoV zafi birgima karfe zagaye sanduna

Karfe Cr12MoV yana da ƙarfin ƙarfi, kuma waɗanda ke da sashin giciye na 300 zuwa 400 mm ko ƙasa da haka za a iya kashe su gaba ɗaya.
Zai iya kula da taurin mai kyau kuma ya sa juriya a 300 ℃ 400 ℃, taurinsa ya fi girma fiye da karfe Cr12, kuma canjin ƙarar sa yana da ƙarancin lokacin quenching. Ana iya amfani da shi don ƙera nau'i-nau'i daban-daban da kayan aiki tare da manyan sassan giciye, siffofi masu rikitarwa, da kuma tsayayya da manyan nauyin tasiri. Misali, naushi ya mutu tare da hadaddun sifofi, abubuwan da ake sakawa a kan matattun mutuwa, zane mai zurfi na karfe ya mutu, zanen waya ya mutu, farantin waya mai zare, mutuwar sanyi, almakashi yankan sanyi, madauwari saws, daidaitattun kayan aikin, kayan aikin aunawa, da sauransu.
Cr12MoV karfe ne babban carbon, high-molybdenum lysic karfe. Abubuwan da ke cikin carbon ɗinsa sun fi na Crl2 ƙarfe ƙasa kaɗan, kuma an ƙara shi da molybdenum da abubuwan vanadium, waɗanda ke haɓaka haɓakar sarrafa zafin jiki na ƙarfe, tasiri mai ƙarfi da rarraba carbide. Karfe yana da babban juriya na lalacewa, taurin kai, tauri, tauri, kwanciyar hankali na thermal, ƙarfin matsawa, kazalika da nakasar micro, ingantaccen aiki mai fa'ida da daidaitawa mai yawa. Zafin laushi mai zafi shine 520 ℃. Girman yankewa yana ƙasa da 4mm kuma ana iya taurare gaba ɗaya. Rashin juriya na wannan karfe yana da sau 3 ~ 4 mafi girma fiye da na ƙananan kayan aiki na kayan aiki, kuma ƙarar quenching yana da ƙananan. Hardening zurfin: man quenching 200 ~ 300mm.
A lokacin aiwatar da crystallization, an samar da adadi mai yawa na eutectic farin carbides (ƙarancin abubuwan da aka yi da carbonized shine kusan 20%, kuma zafin eutectic yana kusan 1150 ° C). Wadannan carbides suna da wuyar gaske kuma suna da rauni. Duk da cewa carbides sun karye zuwa wani mataki bayan billet ɗin billet, ana rarraba carbides a cikin makada, shinge, tubalan, da tarawa tare da jujjuyawar, kuma matakin rarrabuwa yana ƙaruwa tare da diamita na ƙarfe.
